yea Im also overjoyed, +128 grams of top quality, super compact Bud`s plus a lot of trim, and its my first time flowering with LEDs, great Par light and great light output and penetration, according to my light meter almost as strong as my 600W HPS and for sure better spectrum/Par light
totaly blew my expectations for LEDs, did want one for some time now, and after reading a lot of bad reviews, I just had to see for myself, and yes your friend is right, if we talk cheap 1W Chinese LEDs with only/mainly blue/red LEDs but he is totally wrong when we talk quality LEDs
IME only down side LEDs have compared to HIDs is the space they cover, like somebody already said, you need to keep your plants pretty much under them as they are pretty one directed, but not that close as other mention, I found that 14-16 inch`s is the best distance, closer then 12" and they are to strong and will bleach your plant tops (did it on 3 of mine in the center of the light) at 15" my light meter still show +5K foot candles, same I had with my 600W HPS at the top of the plants, but the LEDs provide it in much better Par and with much less power used and next to no heat
but tell me, you spend +3K $ on that set up but you don't owen a camera ? or even a smart phone or any phone with a camera in it ? pictures is a good thing to add in here for fast respond and better advice and of course fun
